Abstract
The invention particularly relates to a method for improving iSCSI protocol conformance test software iscsisim. According to the method for improving the iSCSI protocol conformance test software iscsisim, a PDU message comparison module is added for analyzing a received PDU message of a target end and a local PDU message verification file in a key-value manner and comparing whether value values with the same key value are correct, so as to determine whether the PDU message satisfies protocol conformance; and a protocol negotiation result module is further added for storing a protocol option negotiated with the target and specifically supported by the target, and iscsisim selects a test option supported by the target according to the option to carry out a protocol conformance test. According to the method for improving the iSCSI protocol conformance test software iscsisim, the PDU message comparison module is added to verify the conformance of the PDU messages, the target replies a keyword sequence of the PDU message for decoupling, the flexibility of the iscsisim is improved, and the protocol negotiation result global module is added to automatically eliminate test of the options not supported by the target, thereby reducing the manual selection and improving the test efficiency.
Description
Technical field
The present invention relates to iSCSI Protocol conformance testing technology field, particularly the improving one's methods of a kind of iSCSI testing protocol consistency software iscsisim.
Background technology
SCSI(SmallComputerSystemInterface) be for I/O equipment, especially memory device carries out mutual protocol family.SCSI client, i.e. " initiator ", the logical block to server end (i.e. " target ") sends scsi command with request service.The client-server end of SCSI agreement is mapped to specific interconnected systems by " SCSItransport ".Initiator is one end of SCSItransport, and target is the other end.
ISCSI(InternetSmallComputerSystemInterface) agreement uses TCP/IP as SCSItransport.By transmitting scsi data bag on TCP/IP, iSCSI provides a kind of solution of interoperable, which utilizes existing Internet infrastructure and management tool, and breaches distance limit.Different from needing the traditional fiber of client cables, iSCI can run in existing network system.Due to its extensibility and economic benefit, iSCSI has become popular SAN(Storageareanetwork) agreement.ISCSI defines in IETFRFC3720iSCSI, and upgrades in IETFRFC5048iSCSICorrectionsandClarificationsRFC.
Current iSCSI protocol conformance software I scsisim testing process, as shown in Figure 1.The principle that Iscsisim tests mainly is sent by simulation initiator end and tests PDU message and consult PDU message to target end, and after the PDU message receiving the reply of target end, whether verification target holds protocol realization consistent.Current iscsisim test directly by PDU message and local PDU verification file one by one keyword carry out parsing and compare.But the PDU message keyword order that different target replys is variant, need to adjust local PDU message checking file according to PS when testing different target, and protocol negotiation result is not preserved in current iscsisim test, cannot reject according to negotiation result the test item that current target do not support.
For the problems referred to above, the present invention proposes improving one's methods of a kind of iSCSI testing protocol consistency software iscsisim.Be intended to the flexibility increasing iscsisim, realize automatic rejection target and do not support that item is tested, reduce artificial selection, improve testing efficiency.
Summary of the invention
The present invention, in order to make up the defect of prior art, provides a kind of cost low, and the iSCSI testing protocol consistency software iscsisim that efficiency is high improves one's methods.
The present invention is achieved through the following technical solutions:
A kind of iSCSI testing protocol consistency software iscsisim improves one's methods, and it is characterized in that comprising the following steps:
(1) iscsisim software simulation initiator holds and sends negotiation PDU message to target end;
(2) after iscsisim software receives target negotiation packet, by the protocol option that the target that protocol negotiation object module is preserved and target consults specifically supports, the test option that iscsisim selects target to support according to this option carries out testing protocol consistency;
(3) iscsisim software sends test PDU message according to the protocol option simulation initiator consulted to target;
(4), after iscsisim software receipt to PDU message, whether protocol conformance is met by the verification of PDU message comparison module.
In described step (2), after iscsisim and target holds the good protocol fields of initial negotiation, iscsisim preserves the result after consulting by protocol negotiation object module global variable; In described step (4), iscsisim reads local corresponding PDU message checking file according to the protocol fields consulted.
In described step (4), described PDU message comparison module resolves the PDU message of the target end reply received and local PDU message checking file respectively in key-value mode, then whether the value value of more identical key value is correct, to determine whether PDU message meets protocol conformance.
When iSCSI agreement does not support HeaderDigest agreement item, target end is replied PDU message and is not supported HeaderDigest, iscsisim preserves this negotiation result, reject the test case comprising test HeaderDigest test item, send other test cases, iscsisim resolves in key-value mode and receives PDU message and local PDU message checking file, compares the value value that key is identical, judges whether to meet protocol conformance with this.
The invention has the beneficial effects as follows: this iSCSI testing protocol consistency software iscsisim improves one's methods, PDU message consistency desired result and the decoupling zero of target reply PDU message keyword order is achieved by increasing PDU message comparison module, add the flexibility of iscsisim, by increasing protocol negotiation result global module, achieve automatic rejection target and do not support that item is tested, decrease artificial selection, improve testing efficiency.

Embodiment
Accompanying drawing is a kind of specific embodiment of the present invention, and below in conjunction with accompanying drawing, the present invention is described in detail.
This iSCSI testing protocol consistency software iscsisim improves one's methods, and comprises the following steps:
(1) iscsisim software simulation initiator holds and sends negotiation PDU message to target end;
(2) after iscsisim software receives target negotiation packet, by the protocol option that the target that protocol negotiation object module is preserved and target consults specifically supports, the test option that iscsisim selects target to support according to this option carries out testing protocol consistency;
(3) iscsisim software sends test PDU message according to the protocol option simulation initiator consulted to target;
(4), after iscsisim software receipt to PDU message, whether protocol conformance is met by the verification of PDU message comparison module.
In described step (2), after iscsisim and target holds the good protocol fields of initial negotiation, iscsisim preserves the result after consulting by protocol negotiation object module global variable; In described step (4), iscsisim reads local corresponding PDU message checking file according to the protocol fields consulted.
In described step (4), described PDU message comparison module resolves the PDU message of the target end reply received and local PDU message checking file respectively in key-value mode, then whether the value value of more identical key value is correct, to determine whether PDU message meets protocol conformance.
When iSCSI agreement does not support HeaderDigest agreement item, target end is replied PDU message and is not supported HeaderDigest, iscsisim preserves this negotiation result, reject the test case comprising test HeaderDigest test item, send other test cases, iscsisim resolves in key-value mode and receives PDU message and local PDU message checking file, compares the value value that key is identical, judges whether to meet protocol conformance with this.
